IBM 1800 Data Acquisition And Control System
The IBM 1800 Data Acquisition and Control System (DACS) was a process control variant of the IBM 1130 with two extra instructions (CMP and DCM), extra I/O capabilities, 'selector channel like' cycle-stealing capability and three hardware index registers. IBM announced and introduced the 1800 Data Acquisition and Control System on November 30, 1964, describing it as "a computer that can monitor an assembly line, control a steel-making process or analyze the precise status of a missile during test firing." Overview Unlike the 1130, which was a desk-like unit, the 1800 is packaged in 6 foot high, EIA Standard 19 inch racks, which are somewhat taller than the racks used by S/360 systems of the same vintage, but the internal gates and power supplies were very much the same. Many 1800 cabinets show a distinct "ding" on the vents at the top of the chassis, where movers discovered that the door into a computer room was not quite tall enough for the 1800 cabinet. The IBM 1500 ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minicomputer
A minicomputer, or colloquially mini, is a class of smaller general purpose computers that developed in the mid-1960s and sold at a much lower price than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, ''The New York Times'' suggested a consensus definition of a minicomputer as a machine costing less than (), with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to original equipment manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (1965–1985), almost 100 companies formed and only a half ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 2841
Beginning with its 1964 System/360 announcement, IBM's mainframes initially accessed CKD (Count key data) subsystems via a channel connected to separate Storage Control Units (SCUs) with attached Direct Access Storage Devices (DASD), typically a hard disk drive. This practice continued in IBM's larger mainframes thru System/370; however low end systems generally used lower cost integrated attachments where the function of the SCU was combined with that of the channel, typically called an Integrated File Adapter. The System/360 selector channel was followed by the System/370 block multiplexor channel which could operate as a selector channel to allow attachment of legacy subsystems. The SCU evolved into a Director and Controller, the latter typically labelled an "A-unit" (or A-Box") with the controller and at least one DASD physically in an A-unit. An Integrated Storage Control (ISC) is a Director within the cabinet of an IBM System. A Director could attach from one to four A ...

IBM System/7
The IBM System/7 was a computer system designed for industrial control, announced on October 28, 1970 and first shipped in 1971. It was a 16-bit machine and one of the first made by IBM to use novel semiconductor memory, instead of magnetic core memory conventional at that date. IBM had earlier products in industrial control market, notably the IBM 1800 which appeared in 1964. However, there was minimal resemblance in architecture or software between the 1800 series and the System/7. System/7 was designed and assembled in Boca Raton, Florida. Hardware architecture The processor designation for the system was IBM 5010. There were 8 registers which were mostly general purpose (capable of being used equally in instructions) although R0 had some extra capabilities for indexed memory access or system I/O. Later models may have been faster, but the versions existing in 1973 had register to register operation times of 400 ns, memory read operations at 800 ns, memory wri ...

IBM 7700 Data Acquisition System
The IBM 7700 Data Acquisition System was announced by IBM on December 2, 1963. It is capable of collecting data from as many as 32 sources simultaneously, process the data and transmit results to up to 16 remote printers, display units or plot boards. The IBM 7700 was short-lived, being replaced by the IBM 1800 Data Acquisition and Control System on November 30, 1964. Two IBM 7700 Data Acquisition Systems are known to have existed: one at the University of Rochester and the other at Stanford University. Both were donated by IBM. The IBM 7700 is an 18-bit system, with instructions occupying two 18-bit words. Arithmetic instructions generally execute in two or three machine cycles, except for multiply, about 8 cycles, and divide, 12 cycles. A machine cycle is two microseconds. Address space is 262,144 words, but the two machines known to have been built had 16,384, 32,768 or 49,152 words. The IBM 7700 is contemporary with the IBM 7000 series The IBM 700/7000 series is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pickering, Ontario
Pickering (2021 population 99,186) is a city located in Southern Ontario, Canada, immediately east of Toronto in Durham Region. Beginning in the 1770s, the area was settled by primarily ethnic British colonists. An increase in population occurred after the American Revolutionary War, when the Crown resettled Loyalists and encouraged new immigration. Many of the smaller rural communities have been preserved and function as provincially significant historic sites and museums. The city also includes the development of Durham Live, a multi-billion-dollar casino complex. History Early period The present-day Pickering was Aboriginal territory for thousands of years. The Wyandot (called the Huron by Europeans), who spoke an Iroquoian language, were the historical people living here in the 15th century. Archeological remains of a large village have been found here, known as the Draper Site. Later, the Wyandot moved northwest to Georgian Bay, where they established their historic homela ...

Token Ring
Token Ring network IBM hermaphroditic connector with locking clip. Screen contacts are prominently visible, gold-plated signal contacts less so. Token Ring is a computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a ''token'' that is passed around a logical ''ring'' of workstations or servers. This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention-based access methods. Token Ring was a successful technology, particularly in corporate environments, but was gradually eclipsed by the later versions of Ethernet. History A wide range of different local area network technologies were developed in the early 1970s, of which one, the Cambridge Ring, had demonstrated the potential of a token passing ring topology, and many teams worldwide began working on their own implementations. ...
